Extremism Can Be Deadly

A warning has been sent to us from across the Atlantic. It's a message that perhaps has been muffled by our own domestic tragedies, in the murder of British politician Jo Cox.

Her killer, so unrepentant and proud, was and is likely not alone in his views: He must act violently to silence another view. A compromise, a democratic debate, a due process -- it was never a choice. It was his way or death.

Before there was 9/11, there was the Oklahoma City bombing and Timothy McVeigh. We forget when we need to remember what created him, what made him do what he did -- even what his national origin and skin color was.
